Trap



Aug. 11, 1936- c. L. MYERLY TRAP Filed July 17, 1935 Patented Aug. 11,1936 UNITED STATES PATENT OFFICE 1 Claim.

This invention discloses a trap for water of condensation or the like,characterized by a novel, float operated valve construction, by a novel,builtin sediment chamber, and by other advantages incident to thedetails of structure hereinafter described. A mechanic who works withinthe scope of what is claimed need not adhere to the precise structuredescribed and depicted.

Fig. 1 is a vertical section of the trap, and Fig. 2

is a plan of the receptacle, minus the lid.

For convenience in describing the relative location of parts, theforward end of the trap is marked by the letter A and the rear end bythe letter B.

There is provided a receptacle I including a body 2 having a narrowedrear extension 3, the bottom of which is higher than the bottom of thebody proper. A lid 4 is detachably secured at 5 to the body 2 and has anupward bulge 6,

carrying a petcock 1, under the control of an operator, and used to ventthe receptacle of air, upon occasion. The lid 4 has 2. depending lug 8,located in the extension 3 of the body 2. The bottom of the extension 3is provided with a bore 9 into which an outlet pipe I0 is threaded. Avalve support H is threaded into the bottom of the extension 3 and has aduct I2 communicating with the bore 9. There is a curved seat I4 in theupper end of the support II. A valve I5 is provided and has a curvedlower end I6, convexed to fit fluid-tight in the concaved seat I 4 ofthe support H. The valve I5 is kept in place by gravity. The valve [5has an angular passage I1, the forward end of which communicates withthe receptacle I, by way of the extension 3 of the body 2. The lower endof the passage I1 is adapted to be closed by the seat M of the supportII when the valve 15 is in the vertical position of Fig. 1. The upperend i8 of the valve i5 is tapered, and is located directly beneath thelug 8 on the lid 4. The space between the upper end of the valve l5 andthe lug 8 is less than the depth of the seat Hi in the support II, andthe valve l5, therefore, cannot become detached from ,5 the support H.The rear side of the valve I5 is cut away at l9, so that the valve cantilt enough to bring the lower end of the valve passage I'l intoregistration with the duct l2 of the valve support H.

50 The means for operating the valve [5 embodies an arm 20 secured tothe valve and carrying a float 2| located in the receptacle I.

An inner baflle 22 is interposed between the float 2| and the inlet pipe26 for the receptacle 55 l, the inlet pipe being mounted in a bore 25formed in the body 2. The inner bafile 22 is connected to the bottom ofthe body 2 and to the sides thereof. An outer baffle 23 is disposed infront or" the inner baiiie 22, the outer baffle extending upwardly intocontact with the lid 4, 5 the vertical edges of the outer baffle beingconnected to the sides of the body 2. The bafile 22 and the adjacentportions of the body 2 of the receptacle form a sediment chamber 21. Aplug 24, threaded into the body 2, or some equivalent 10 for the plug,constitutes means under the control of an operator for draining sedimentout of the chamber 21.

The water enters the receptacle l by way of the pipe 26 and the bore 25.The water is di- 15 rected downwardly into the sediment chamber 21, bythe bafile 23, and upwardly into the float chamber receptacle, by thebafile 22. The sediment can be drawn ofi at any time by removing thepart 24.

The water enters the float chamber of the receptacle I, raises the float2!, and tilts the valve l5, by way of the arm 20, until the lower end ofthe passage I! in the valve l5 registers with the duct i2 of the valvesupport II. This permits the water to run off through the pipe 10. When2 enough water has been drained OK, the parts resume, approximately, thepositions indicated in Fig. 1, the valve passage l'l being closed. Theelongated form of the valve l5 enables the passage I'! to rock out ofregister with the duct l2 by a motion at right angles to that impartedby the float 2|.

The device, among other features, is characterized by a novel, built-indirt catcher, by a novel, 3r fioat operated valve, which isself-grinding, and o by novel means for keeping the valve in place, itbeing possible to remove the valve and its float by taking ofi the lid4, the lug 8 on the lid then being removed from its position above thevalve. 40

What is claimed is:

In a device of the class described, a receptacle having an inlet, avalve support mounted on the bottom of the receptacle and provided inits upper end with a concaved seat, the receptacle being provided withan outlet including a duct in the valve support, the duct leading to theseat,

a vertically-elongated valve of greater height than diameter, having aconvexed lower end shaped to fit closely upon the seat and mounted torock therein, the valve having an angular borelike passage, adapted tobe closed by the seat but registering with the duct when the valve isrocked to a given position, the intake end of the passage being spacedfrom the seat, a float in the receptacle, and an arm connecting thefloat with the valve, the engagement of the upper portion of theelongated valve with the receptacle preventing the passage from rockingout of registration with the duct by a motion at right angles to thatimparted by the float, in the normal operation of the valve, andenabling the arm to be connected to the valve far enough from the seatto reduce the rocking movement of the valve to what is needed to makethe valve self-grinding,

the receptacle having a depending lug disposed above the valve, the lugbeing spaced from the valve and being independent of the valve in thenormal operation of the valve to govern the flow of liquid from theinlet to the outlet, the lug constituting a stop for the valve, under anabnormal lift, and then returning it to its normal working position.
